The reply will depend on quite a few elements. These embody: (i) are there interactions between the entity and the setting, (ii) does the mannequin have a time element, (iii) is the mannequin a cohort or particular person stage mannequin, (iv) is the mannequin steady or discrete states, and (v) is it Markovian or not. The Brennan taxonomy of mannequin constructions helps present an summary of which mannequin sort to select primarily based on these concerns.
To supply some examples of what Breeze et al. (2023) phrases advanced techniques fashions:
Computable Common Equilibrium (CGE) fashions have been used to mannequin selections which have cross sector impacts that affect the indications of the nationwide economic system. Partial differential equation fashions can be utilized to explain the dynamics of infectious illness transmission. Each CGE and Partial differential equation fashions have key similarities to system dynamics and describe aggregated populations. In infectious illness modeling, the time period individual-based mannequin is usually used for ABMs [agent-based models]. IBMs have lengthy been used to incorporate spatial and social inhabitants construction related to transmission and have been generally utilized in modeling COVID-19 and impacting coverage choices. IBMs enable straightforward inclusion of behavioral change to challenge its results on transmission dynamics
